Cement is a single material, which can be used to fill some gaps in many cases. In addition, other materials can be added or used individually. Its strength selection is relatively more, not only one choice, because it will be used when the project is carried out again.
预制工厂中基本上都对井盖模具的加工环境都是选择了光滑的水泥地面，四周有着防护的工具，可以保证好井盖模具在加工的时候不会受到其他问题的影响，自然也就能够放心来进行使用了。
The prefabrication factory basically selects the smooth cement floor for the processing environment of the well cover mold, and there are protective tools around, which can ensure that the well cover mold will not be affected by other problems during processing, so it can be used with confidence.
现在的井盖模具不仅仅是硬度有所提高了，在井盖模具外侧的延长筋厚度也进行了细微的调整，这样可以让模具在长时间加工时没有变形的风险
Now the hardness of the well cover mold is not only improved, but also the thickness of the extension rib on the outside of the well cover mold is slightly adjusted, so that there is no risk of deformation when the mold is processed for a long time
同样保证了预制件制作完成后的质量，也可以有效的延长井盖模具的使用时间，其他材料准备齐全后工人就可以按照预知的步骤进行井盖模具的使用了。
It also ensures the quality of the prefabricated parts after fabrication, and can effectively prolong the service time of the well cover mold. After other materials are fully prepared, the workers can use the well cover mold according to the predicted steps.
